Mobil 1 synthetic after 1 Million Miles

Here is a good video showing how Mobil1 is protective after one Million Miles. Almost no signs if wear, No deposits, no Cylinder wear and no combustion and valve deposits. Just Amazing. Mobil1 is truly the King. this is why its a standard in AMG engines

Doesn't most engine wear occur at cold startup/warmup? The video says the test ran night and day, presumably stopping only for maintenance.

I doubt they even let the engine cool while stopping for gas, that is if they used the stock fuel tank as it would require 2500 fuel ups at 400 miles/tank. They could have just as easily hooked it to something capable of doing 7500 miles as that is the drain interval on the oil.

Also, what kind of dyno is that? If it's not simulating the load of driving on the drive train, this test cannot be used to judge the product's longevity on the road.

It doesn't surprise me that an engine which was meticulously maintained and ran under controlled conditions showed such little wear. Now if they did the test along side another car which was using traditional oil with traditional drain intervals, that would be interesting. However, this test is lacking any context.

This is a marketing tool from Mobil1, not a peer reviewed study. Take it with a grain of salt.
